可以, 你trust自己張self sign cert就得
你set個https比localhost server咪得
唔係喎
http應該可以access到https架
唔係https先access唔到http咩
ailed to load resource: the server responded with a status of 403 ()
如果只係圖既話最多都係tag你個page做mixed content
唔會唔比access
有trade 有settlement 又管人少user support
好似重要識少少 script 同manage vendor 不過好似好多野學
但乜都要做同真係幫手做oper settlement
駛唔駛做埋account, budget, project management, security
平時user support有vendor 應該好少少
Imgur 用CDN
我改返咗local host唔係用
0.0.0.0冇問題了thanks
唉 沒有空 我要在3日之內建立20個web 類似有db 的
整到成個json 做array 但search 起來 像有db 運作中的web
其實簡單嚟講都係control framework
Ensure IT procedures and controls are adhered to regulatory requirements and company policies.
Undertake regular IT related tasks such as P-Test, BCP, DR Test, etc.
呢啲啱我😂😂
Anyways, control framework 如果唔係叫你落手砌control, 其實冇乜難度
High level 定 low level control sin?
不過冇banking license 輕鬆啦
SFC 都係得 EDSP 嗰啲
拆開做30K it support + 50k internal auditor/cyber sec specialist 唔係好啲咩
做做下policy 走去support 😂都幾開心
佢似要technical 人但係做埋 policy and procedure
真做我依家條team working level 80-90k 都有
總之就係 src MAC 係中移動 dst MAC 唔係自己
其實有冇regulation 都係呢啲人工
純粹internal payscale
我相信係中移動 port 傻咗，send 咗啲唔係去 HKIX 嘅 packet 過去
HKIX 見到啲未見過嘅 mac address 就一直 flood 晒所有 port
他不是將d packet send 了所有的port mac address
Emm正常唔是有啲measure 防止looping 咩
但係 HKIX 部 switch 一直 learn 唔到就一直 flood
用來給cisco switch 建立私家路去嗰個port
但佢唔係invalid既野 只係bug左咁send錯野可以點prevent
flush MAC address table 係咁大規模會出事
爆左mac addr table應該連command都好難行
i mean, one packet in becomes many packets out
then you would have more out than in
淨係lab玩過hyena flood mac table
一個software random gen mac addr 再係咁射arp packet 落啲network device?
射到隻router cam table爆炸勁lag
broadcast 要 dst MAC 係全部 ff
依家呢啲叫 flood 😂
我抓頭了 Cisco switch 不是有aging time
src MAC 中移動
dst MAC 正常但係唔係 HKIX port
結果 HKIX 學唔到 dst MAC 就係咁 flood
so it's not broadcast mac but rather hitting high number of packacts that are not in the usual ranges handled by the switches
好彩唔係loop flood......但IX又矛咩理由Flood...
而家d switch唔係識precent flooding attack?
就是講switch 的什麼是Mac addressaging time
因為全部known peers, 唔開可以用少啲hardware
本身hkix自己無收人錢
本身佢arp都learn唔到個時係會flood,但好似係可以discard佢
依家係勁多packet同時間寫入cam table
"HKIX will turn on port security with the MAC address connected from participant's router to the HKIX switch. At any time, only one MAC address will be allowed on each HKIX port and HKIX participant must inform HKIX NOC by email if there is any change or maintenance on the router MAC address."
Only check src MAC for port security
係prevent man in the middle?
port disable, reboot blablabla
router check 唔到
因為我條 HKIX 過咗 switch 先見到
router 自己 discard 咗唔係自己嘅流量
L3 switch is not just a switch lol

做NETWORK / SUPPORT考都話.. 但你software engineer 考黎做咩==...
devops,然後就會走左improve efficiency of networking shit
now it's almost always cloud
you don't touch cisco stuff directly
btw平時呢啲switch呀router點做remote management
😂上面咩講咗 ssh tunnel as example
Diu why not just open ssh at mgmt port
sounds very vendor specific
guessing it means the mgmt port is connected in another network
then i guess the switch and routers of that network also have the mgmt port connected in the same network lol
en
config t
line vty 0 4
transport input ssh
...
which router is holding this lol
then how do i manage this router lol
最好笑係，個 coworking space 冇 client isolation
coworking space ?? 仲有大公司都係VLAN 1 why not
我一吉落去，見到其他房 tenant 啲 printer, NAS, workstation...
this is Hong Kong - Part of Chi na
you are in the same subnet
有啲working space好似係無間開到天花板
其實自己個subnet mask 整大啲食到入個subnet 有冇得諗
Yes but ports can be isolated ah
如果router enforce vlan應該唔得?
Disable unused port
Separate internal client wifi
Set up dmz for external connection
用個好啲既fw
Vlan
🤔
拎住 CCNA，第一日返工老細就同你講，搞好個上網去，咁你可以做咩？
駁router駁modem拉LAN線set DHCP
Check下手上有乜 跟住set 同config lor
要裝port位，整暗線，搵個位放ap router
唔想浪費cpu resource係firewall
想請r&d 既pm 寫到變assistant of it manager
成個IT得一個女既管深圳既dev重要做埋presales
你老味臭閪，又做咗10年咩megai 客戶, 到頭來一啲優惠都冇，我屌柒你老母臭閪呀
你老味淨係識得叫我俾錢，一啲服務提升都冇，我走啦我屌你老母
最好就喺分開起一個 management network
30年前就話得你Iadvantage 勁姐，30年後唔係剩係得你㗎
又唔是checkpoint or cisco dna/meraki
咁vlan over multiple switch有乜用
即是如果隻switch自己tag就有vlan, 無tag就無？
Native vlan 要人手config 跟住untagged package passed through 有specify native vlan 既port就會當係from果個vlan number 既packet咁射走
有d 要打 呢個Switchport mode access ｜ trunk 來改

可能你地69 人有一半以上脫單 有老婆 而我都仲未有
你唔係做coding 嘅話
你唔知道裏面幾辛苦㗎
我哋呢邊有人係凌晨一兩點先收工㗎
我都算好㗎啦九點10點算半個早走㗎喇
如果係做coding 嘅話咪仆街囉 我哋嗰邊好緊張的
